The master report does not show basic subreport with Java Beans at Jaspersoft Studio

问题


I'm having trouble generating a basic report (master/subreport) with JavaBeans in Jaspersoft Studio.

I created TestMainReport.jrxml and TestSubreport.jrxml.

TestMainReport.jrxml contains two static text fields, labeled "A Title" in the title band and "A Summary" in the summary band.

TestSubreport.jrxml contains two static text fields, "Subreport Title" in the title and "Subreport Summary" in the summary band.

I've assigned JavaBeans Data Adapters to them, which are not used (although the JavaBean fields are being mapped in the master report. I just happened to not map them in the subreport since they are not used).

A subreport element has been added to the master report in the Summary band.

Both reports are well generated individually when I try to generate each one. However, the subreport static texts won't appear in the master report.

I was expecting that the subreport's static texts would appear in the master report.

What am I doing wrong?

What is wrong?

You did not specify dataSource for subreport. Instead of this you have set connectionExpression (<connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression>). The connection can help you in case jdbc based datasources (reports), but not at your case.

Solution1 - Using dataSourceExpression

You should specify datasource for subreport. You can declare subreport element like this:

<subreport>
    <reportElement x="0" y="30" width="560" height="150"/>
    <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource(testdatasource.CustomerAddressDataSource.getCustomerAddresses())]]></dataSourceExpression>
    <subreportExpression><![CDATA["TestSubreport.jasper"]]></subreportExpression>
</subreport>

In this case CustomerAddressDataSource class will be used for filling subreport.

Solution 2 - Using external definition of Data Adapter

You can export Data Adapter of subreport to the file and save it to the same folder as templates (if you don't want to specify path to data adapter file).

You can export Data Adapter definition with help of context menu at JSS (Jaspersoft Studio):

In your case - it will be CustomerAddressesDataAdapter.xml with this content:

<?xml version="1.0" encoding="UTF-8" ?>
<beanDataAdapter class="net.sf.jasperreports.data.bean.BeanDataAdapterImpl"><name>Customer Addresses Data Adapter</name><factoryClass>testdatasource.CustomerAddressDataSource</factoryClass><methodName>getCustomerAddresses</methodName><useFieldDescription>false</useFieldDescription><classpath>C:\somepath\library_with_beans.jar</classpath></beanDataAdapter>

You should specify this adapter at subreport with help of net.sf.jasperreports.data.adapter property. With help of this property you should specify name of file with Data Adapter definition (description), it can be name with path. At my case it will be: CustomerAddressesDataAdapter.xml.

The subreport template will be:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="TestSubreport" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">
    <property name="net.sf.jasperreports.data.adapter" value="CustomerAddressesDataAdapter.xml"/>
    <title>
        <band height="79" splitType="Stretch">
            <staticText>
                <reportElement x="0" y="0" width="100" height="30"/>
                <text><![CDATA[Subreport Title]]></text>
            </staticText>
        </band>
    </title>
    <summary>
        <band height="42" splitType="Stretch">
            <staticText>
                <reportElement x="0" y="0" width="100" height="30"/>
                <text><![CDATA[Subreport Summary]]></text>
            </staticText>
        </band>
    </summary>
</jasperReport>

At master report the section with subreport will be:

<subreport>
    <reportElement x="0" y="30" width="560" height="150"/>
    <subreportExpression><![CDATA["TestSubreport.jasper"]]></subreportExpression>
</subreport>

- as at previous case you don't need to specify connection.

As for the first solution the output result at JSS will be:
